The Event (Studies in Continental Thought) (Martin Heidegger (Author, Editor), Richard Rojcewicz (Translator), Indiana University Press, 2012)

Martin Heidegger’s The Event offers his most substantial self-critique of his Contributions to Philosophy: Of the Event and articulates what he means by the event itself. Richard Rojcewicz’s elegant translation offers the English-speaking reader intimate contact with one of the most basic Heideggerian concepts. This book lays out how the event is to be understood and ties it closely to looking, showing, self-manifestation, and the self-unveiling of the gods. The Event (Complete Works, volume 71) is part of a series of Heidegger's private writings in response to Contributions. (amazon) (accessible via scribd)

This is a translation of Martin Heidegger’s Das Ereignis. 
The German original was composed in 1941–42 and was published posthumously in 2009 as volume 71 of 

the author’s Gesamtausgabe (“Complete Edition”). 
The book is the sixth in a series of seven reflections 
inaugurated by the decisive Contributions to Philosophy 
(Of the Event). At the heart of all these reflections is what 
Heidegger calls “the event,” and the title of the present volume thus indicates its close connection to Contributions 
and its centrality to Heidegger’s path of thinking.
